Overview

The Fastest Car You Will Ever Build in Your Garage.

The GTM is our flagship supercar, and has come to symbolize our technological abilities. The car is drop-dead gorgeous and it runs with the very fastest supercars on the planet. Every drive in a GTM is accompanied by camera phones stuck out the window of other cars and thumbs up from other drivers. More than the rock star looks, this car is simply the most brutally fast machine you will ever build.

“Fitted with a 400 HP LS6 engine, it goes ballistic in a blink, rocketing 0-60 in 3.2 seconds... Corvette brakes bring the GTM to a clenching halt in only 111 feet from 60 MPH. Street tires deliver 1.05 Gs on the skid pad!”VETTE MAGAZINE

Get Ready to Build Your GTM!

KIT STARTS AT $24,990

The GTM Supercar kit is engineered to be built by a person at home with regular tools. The GTM kit gives you everything you need to build your car, except for running gear parts taken from a 1997-2004 Chevrolet C5 Corvette and a transaxle. The major Corvette parts include the engine, front and rear control arms, suspension/brakes, and fuel tanks. The transaxle used is a Porsche 911 unit or a Mendeola 5 speed.

Design

Aluminum Under Glass

The Factory Five GTM uses an ultra-strong space frame and is joined by a matrix of aluminum sub-frame panels to complete a true race-car construction. Built on the strong foundation of this tough chassis is a four corner coil-over shock suspension with unequal length control arms and massive Corvette brakes. The composite body rests on top of this chassis and is a separate unstressed assembly.

Modern Design and Engineering

At the very core of the GTM Supercar is a computer designed, ultra-rigid space-frame. The frame is made of mig-welded, high strength mild carbon steel tubing and plate steel. This special design incorporates a low center of gravity, high torsional rigidity, and solid safety features that delivers true supercar performance in a safe and secure vehicle design.

GTM Running Gear

The GTM uses the proven running gear from GM’s world-class Corvette and Corvette Z-06. Major assemblies include engine, computer engine controls, fuel system, and front and rear suspension/braking. The GTM is designed to accept GM LS series engines. From the proven 350 HP LS1 to the potent 430 HP LS3s and 500+ HP LS7s.

Competition Capable and Fully Streetable.

We’ve already proven the GTM suspension in conditions more demanding than you ever will. We’ve competed in the 25 Hours of Thunderhill for more than five years. The GTM was developed and tested on the racetrack, at the dragstrip, at autocrosses, and ultimately in the real world out on the streets.

Performance Automotive Art.

The GTM has pure supercar lines. Low, menacing and powerful… those are the words that come to mind when one sees the GTM in person for the first time. But looks have to support function. No matter how fast a sports car is, it has to look good. That’s why we developed this shape in the wind tunnel and at speed on countless racetracks over a process of five years.

Press

“Perhaps the best part of the GTM is that after blowing off pedigreed cars during a track day, the owner can make a boast no one else can: ‘I built it.’”

Larry Webster, EditorCar & Driver

“I was enamored with the GTM’s power-to-weight ratio, exemplary road manners and handling composure, reasonably comfortable interior, and down right sexy looks. Factor in the affordable entry price and the reliable C5 mechanicals and the GTM becomes a refreshingly simple, attainable, and even practical alternative to today’s mainstream supercars.”

Corvette Magazine

“...the car trips to 60 MPH in three seconds flat and clears the quarter-mile in 11.0 seconds at 132 miles per hour. And that, amigos, is quicker than a Porsche Carrera GT, a Ferrari 599 Fiorano, and a Z06 Corvette.”

Larry Webster, EditorCar & Driver Magazine

“...if you even look at the gas pedal, it will flatten your face in an instant.”
